SPECIFICATION forming part of Letters Patent No. 547,980, dated October15, 1895.

' Appunti@ inea May s1, 1895. serrant. 551,133. (Neuman.)

To @ZZ whom, t may concern: Be it known that I, CHARLES BOULAY, acitizen of the United States, and a resident of Barre, county ofWorcester, and State of Mas- 5 sachusetts, have invented certain new anduseful Improvements in Machines for Upset-y ting Wagon-Tires, of whichthe following Ais a speciiication, reference being had to thezac-vcompanying drawings, forming a part thereof, 1o in which similar lettersand figures of reference indicate corresponding parts.

My invention relates to machines for upsetting wagon-tires, and is animprovement on the construction 'shown and described in 15 United StatesPatent No. 535,481, granted to me March l2, 1895.

The obj ect of the'present invention is to produce means by which themechanism covered by my patent referred to may bemore easily zo operatedand be more simple and effective in its construction and operation.

The invention is fully disclosed in the following specication, of whichthe accompanying drawings form a part, in which-h 25 Figure lis a sideelevation of my improved machine; Fig. 2, a similar view showing theoperating parts in different positions, and Fig. 3 avertical transversesection on the line 2 2 of Fig. 1.

My invention relates especially to machines for automatically clamping awagon-tire and upsetting the same while the metal is hot, the objectbeing to overcome the objections incident to the ordinary methods ofupsetting 3 5 tires, where the metal is liable to cool while the tire isbeing clamped.

The nature and operation of the machine, Atogether with that of theimprovements and the advantages secured by the latter, will be 4oreadily understood by all conversant with such devices from thefollowing description, when taken in connection with the accompanyingdrawings.

In the practice of my invention I providea 45 body A for the machine,which consists of a plate having a reinforced or thickened edge 50, saidbody portion being approximately triangular in section. An arm B ispivoted at cl to the apex or extreme upper portion of the 5o body A andis adapted to swing laterally to and from said body, and ou the lowerend of the body portion there is an arc-shaped or segmental lug q,curved or formed on a circle of which the pivot d of the arm B is thecenter. The arm B has formed thereon near its lower end a similar curvedflange or lug r, lying in or forming an arc of the same circleandregistering with the flange or lug q when the parts are in the normalposition,and projecting downwardly from said flange or lug r the arm Bis provided with an extension or lug D.

On the lower end of the body A, and preferably at the right-hand sidethereof, isa lug or extension m, with which is pivotally connected avertically-swinging forked or divided arm k, said arm being adapted toinclose between the sides thereof the lug or extension D on the arm B,inwhich is formeda slot D', through which is passed a pin D2, secured tothe sides of the arm k, and in the free ends of said arm a lever O ispivoted at J, the end of said lever adjacent to the pivotal connectionbeing provided with a segmental gear g, which meshes with a similar gearor teeth 1I on the outer edge of the extension or lug D.

, Pivoted in suitable bearing 15 on the arm B is a cam or dog w, and onthe lower end of the body or thickened side 5() of the body A is pivoteda similar cam or dog to2, said dogs being designed to clamp the tire Hagainst the segmental flanges or lugs fr and q, respectively, ashereinafter described. A sliding bar or plate 17 is fitted to movevertically in a suitable slot in the body A and bears on its lower end aclamping-shoe 16 on the front of the body A, the lower surface of whichshoe is serrated or provided with teeth or projections, as shown, bywhich it is enabled to more securely grasp and hold the tire, and at therear of the body A a bar 25 is connected with the sliding bar 17 byset-screws 27, and a coilspring 26 connects the lower end of the bar 25with the body and acts contractivel'y to pull said bar downwardly, aswill be readily understood. A cam-lever t is pivoted at 30 to the rearface of the body A, its outer end projecting beyond the arm B inposition to be en` gaged by a roller ton the lever O, and the inner endof the cam-lever projects into a socket 28 (shown in Fig. 3) in theslidingbar 25. A lever e' has one end pivoted in lugs y on the IOO dogw, its opposite end being slotted at 22 to receive a pivot on the lng orbar 19 on the slide 17, said slot being designed to permit of slightlost motion, as will be hereinafter described. A coil-spring 18 isinterposed between a shoulder on the lever ,e and said lug, and asimilar lever 20 pivotally connects the other end of the lug or bar 19on the slide 17 with lugs :l: on the dog wz.

Near the apex of the body, on the arm B, there is a spring-catch f forthe lever C. When the parts are in the position shown in Fig. 1, theleve'r C is forced from the left to the right, as shown in said ligure,until it is engaged and held by the spring-catch j', in which operationthe roller t, contacting with the cam-lever o, forces the outer end ofsaid cam-lever downward, and the inner end there of being simultaneouslylifted carries the slide 17 upward, thus drawing the clampingslioe 16away from the body or flange q, and by means of the connecting-lever zand 20 also drawing the dogs w and 102 out ofV contact with the flange rand said body or flange q, and sufficient space is thus formed betweenthe clamp-shoe and dogs and the body or anges r and q to admit the tireH. The lever C being released from the catch f, a spring 2G draws slide17 downward, engages the shoe' 16 with the tire, and simultaneauslyspreads the dogs w and w2into contact with said tire, securely clampingthe same against the two flanges r and q. In the further opera-tion ofthe devices the leverC is thrown outward by the operator, which causesthe forked arm la to be thrown or pressed downward, as shown in Fig. 2,while simultaneously therewith the gear g of said lever throws the arm Binward on its pivot d, the pin D2 on said arm, working in the slot D ofthe lug D, guiding the same, so that the flange r is crowded against thetire, which is tightly held by the clamps, thus upsetting the same andcontracting the diameter thereof at this point, as will be readilyunderstood by all those familiar with this class of machines and themethod of operating the same.

The slot 22 of the connectinglever z per mits of the above describedmovement without operating the slide 17, as will be readily understood.

It will be seen that by the use of my device after the lever C is caughtby the springf, elevating the clamping dogs and shoes one continuousoutward movement of said lever effects the secure clamping of the heatedtire in the machine and the upsetting thereof, the operation being sorapid that the metal has no opportunity for cooling.

Pivotally connected with the rear side of the body of the machine orplate A, as shown in dotted lines at A', Fig. 1, isafoot-operated leverA2, having its upward end outwardly curved, as shown at a', adjacent tothe springcatchy, said lever being designed to operate the springftorelease thelever C, as hereinment is to prevent the hulling, swelling,oi"

twisting of the tire, and make sure the upsetting thereof at a singlemovement before it has time to cool, and this the shoe will do withoutexerting great pressure thereon, while the slot D in the extension Dprovides for a more secure connection of the arm 7c, therewith and amore positive action of the connected parts.

Having fully described my invention, its

construction and operation, I claim and desire to secure by LettersPatent- 1. In a machine for upsetting wagon-tires, theicombination witha body portion provided with a segmental base, of a similar segmentalvportion pivoted to said body, a spring-tensioned clamp for securing thetire to said segmental base, a lever and connecting mechanism foractuating said pivoted segment consisting of an arm pivotally connectedwith one side/of t-he body ot' the machine and provided with a pin Whichpasses through aslot formed in the extension or lng connected with saidpivoted segment, said lever being also pivotally connected with the freeend of said arm and provided with a segmental gear which meshes with thecorresponding gear formed en said lug or extension of the pivotedsegment, substantially as shown and described.

2. In a machine for upsetting wagon-tires, the combination with the bodyportion provided with asegmental base, of a corresponding segmentalportion pivotally connected with said body, spring-tensioned dogs on thebody and pivoted segment for clamping the tire thereto, a leverpivotally connected with said body for actuating said pivoted segment,said lever being pivotally connected with an arm which is pivotallyconnected with the body of the machine,` provided with apin operating ina slot formed in an extension of the pivoted segment, said lever beingalso provided with a segmental gear which operates in connection with acorrespondinggear formed on said extension, substantially as shown anddescribed.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of two witnesses, this 14th day of May, 1895.

CHARLES BOULAY.
